A Theoretical Analysis of Distributed Storage System Based on Network Coding
Jiaru Lin · Beijing Youdian Xueyuan xuebao · 2009
To investigate the performance of network coding for distributed storage,a model of that in wireless sensor network(WSN) is brought up.A trade-off relationship between source node degree and the number of queried nodes,i.e.,between network coding complexity and its gain,is set up and proved via bipartite graph model.The performance gain of network coding in distributed storage is analyzed.The results have instructive significance in distributed storage system,especially in the WSN with limited energy consumption.
